Hi, everyone! I assembled a 4-node cluster consisting of 4 Intel processors. I used Fedora Core 4, PETSc 2.3.1 and MPICH2-1.0.3.
There is no problem in installation of PETSc and MPICH2. I also made authorized keys of SSH for connection between nodes without asking password. I confirmed that SSH show no asking of password between nodes. Also, mpdboot for itself is possible like below $ mpdboot -n 1 -f mpd.hosts $ However, mpdboot for multi-processors is not possible by showing the error below. Hostname of node1 is node1.cluster.net and hostname of node2 is node2.cluster.net. $ mpdboot -n 2 -f mpd.hosts mpdboot_node1.cluster.net (handle_mpd_output 368): failed to connect to mpd on node2.cluster.net $ I believe that the things such as /etc/hosts do not have problems. Although it seems a problem of MPICH2, I would like to hear something if you have similar experience like me. Let me know if you have any idea. Thank you so much!
